Accordance doesn't support all of the functionality of the new trackpad on the MacBook Air.

For example missing features include:
1) triple tapping ≠ triple click (even though the system preference is set to make taps = clicks).
2) the two finger expand and contract ≠ increasing and decreasing the font size.

However, other features do, in fact, work:
1) two finder scroll
2) two finger tap = contextual click

My wish is that Accordance supported fully all of the new, exciting, and very useful trackpad fuctionality.
